Citadel

One of biggest mysteries of Utopia, an old structure that has survived countess centuries. The magnificent architecture of Citadel is the last remaining symbol of an ancient civilization that once ruled Utopia. The civilization mysteriously disappeared leaving the citadel behind. The walls of the citadel are donned with images of old gods of the Utopia. When the catastrophe took place, people took shelter in it and it was one of the few things that survived the Catastrophe.
